ADJUSTABLE HUB-PLATE.

Application filed July 21,

To aZZ whom it may concern:

Be it known that I, CHARLES \V. DAKJQ, a citizen of the United States, residing at Chicage, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Adjustable Hub- Plates, of which the following is a specification.

My invention relates to means for taking up or adjusting for wear on the wearing plate associated with a wheel hub, particularly in the case of a locomotive. The invention is illustrated in the accompanylng drawings wherein Figure 1 is a cross section on the line a200 of Fig. 3 with my devices attached;

Fig. 2 is a detail cross section;

Fig. 2 is a modified form of Fig 2;

Fig. 3 is a plan view of the cam surface of the wearing plate;

Fig. 4 is a plan view of the cam surface of the ring;

Fig. 5 is a cross section on the line w-m of Fig. 4.

Like parts are indicated by the same letters in all the figures.

A is the hub,,B the wearing plate, C the ring, the cam surface of the ring consisting of a series or concentric annuli DD, each having a surface which consists of a series of cam surfaces D D These surfaces on each annulus are staggered with reference to those on the next annulus.

Corresponding annuli EE are found on the inner or cam surface of the plate and they also are broken up into a series of cam surfaces E 13 corresponding to the similar surfaces on the ring. 7 V

Associated with the ring and the hub, are a series of dowel-pins FF to prevent the ring from rotating on the plate.

The outer edge of the plate is provided with a series of notches GG with which are Specification of Letters Patent.

is prevented from disengaging itself from the ring C. i

It will be understood, of course, that these varlous parts may be greatly changed in size, proportion and arrangement without departing from the spirit of mv invention. What I have shown is therefore to be taken as diagrammatic, although it does not in the substance set forth a working structure.

The use and operation of my invention are as follows z- Assuming the parts to be constructed as indicated and related as shown in F ig. 1, if the plate 13 should have been worn so as to require adjustment, the pins G are retracted-so as to disengage from the notches G and the plate is turned in the proper di rection on the ring so that the several engaging cam surfaces travel on each other until the plate B has been sufliciently advanced, laterally to accommodate for the wear. The pins G are then screwed forward so as to bring their ends into the notches and the lock screws G are advanced so as to lock the pins G in position and thus prevent further rotation of the plate 1%. During all these actions, the ring C is prevented from rotation by the dowel pin F and the plate B is held in proper contacting relation with the ring C by the coacting flange and lip J and J The plate B may e rotated by any desired means.

By this arrangement of concentric annuli, each consisting of a series of inclined surfaces and these surfaces being staggered with reference to those of the next annulus, a relatively uniform support is furnished for the wearing plate, so as to prevent it from giving or buckling or bending under the strains to which it is subjected.

I have shown five annuli each with two inclined surfaces, There might be any number of annuli greater than one and any number of inclined surfaces on each, from one up. It is only necessary to stagger these surfaces or arrange them so that the end of any one surface is staggered with reference to the adjacent surface on the next annulus to get the desired result. As the action is the same whether there be one or any larger number of inclined surfaces on each annulus, I wish the term series of surfaces as applied to the face of the annulus, to be understood as meaning one or more inclinations.

I have spoken of the hub as having an annular recess but it may easily be understood that the same effect would be obtained by having a flange, plate or ring properly disposed and it will also be understood that the recess could be in the plate and the other projecting parts on the hub. It will also be understood that the recess, as to some features of the invention, might be dispensed with entirely and in such case, the word recess as I use it in the claims, should be understood to refer only to the contacting parts or opposed parts of the plate and hub, although the recess, whether placed on the plate or away, is so minute as to be negligible or entirely dispensable. V

I have spoken of this device as an adjustable hub plate but, of course, it is perfectly obvious that the word hub may here be taken in a broad sense to include any or all parts against which the plate bears and while I have contemplated the application of my invention to the hub of locomotive wheels, it might be used with any other de vice where such an adjustable plate is desired. The word hub therefore, is to be understood as anything which in effect would be the bearing part against which the plate abuts.

I claim:

1. A hub having an annular recess 011 one side, in combination with a ring seated in the recess and having an outer surface which consists of a series of concentric annuli each composed of inclined surfaces staggered with reference to those of the adjacent annulus, and a wearing plate having a projection which extends into the recess and is provided with a surface correspond ing to that of the ring.

3. A hub having an annular recess on one side, in combination with a ring seated in the recess and having an outer surface which consists'of a series of concentric annuli each composed of inclined surfaces staggered with reference to those of the adjacent annulus, and a wearing plate having a projection which extends into the recess and is provided with a surface corresponding to that of the ring, and means for-locking the ring in position while the plate is being turned 4.
